Description

If I want to have multiple versions of Apache Hadoop loaded into my Eclipse IDE today (or any other IDE maybe), I'm supposed to do the following when generating eclipse files, such that the version name is appended to the project name and thereby resolves conflict in project names when I import another version in:

mvn -Declipse.addVersionToProjectName=true eclipse:eclipse

But this does not work presently due to a lack of configuration in Apache Hadoop, which https://jira.codehaus.org/browse/MECLIPSE-702 demands. The problem being that though the project names are indeed named with version suffixes, the "related project" name it carries for dependencies do not carry the same suffix and therefore you have a broken import of projects errors everywhere about 'dependent project <regularname> not found'.

Ideally we need only touch the parent hadoop/pom.xml and it propagates the settings of plugins to rest.
However, I needed to edit the httpfs pom cause it is already overriding the maven-eclipse-plugin ( HDFS-2649 needed/added this) and therefore I have to duplicate the configuration there.
I've added in a comment that indicates it can be removed when the override itself is removed.
I manually tested this with:
mvn eclipse:clean; mvn -Declipse.addVersionToProjectName=true eclipse:eclipse
And then reimported all projects - they carried version suffixes and had no issues with dependencies on one another.

added a comment - 03/May/12 07:24 Actually this whole change can be avoided if one uses M2E plugin for Eclipse. It works fine now (latest updates) with Apache Hadoop projects.
Resolving as not-an-issue. We should just stop using mvn eclipse:eclipse and get it imported inside Eclipse as maven projects instead.
